Experienced mechanics share their insights in answering this question :
Hi there. I wish we could really help you, but the reality is that this type of engine swap always has issues like you’ve described, but the fuse box is only one part of the issue you’re going to have to deal with.The main issue is due to the fact that the ECU and electrical system in the original vehicle does not connection correctly with the newer engine you have installed. Having engines link with the existing ECU happens about 50% of the time. The only way to resolve this problem is to contact a dealership, purchase a new ECU and have them program it to the new engine. In regards to the fuse box, replacing one from the vehicle, not the engine is best.

I have a question, can I replace the ECM on this 2002 Dodge Intrepid engine with a used one?
ANSWER : You cannot install a used ECM that was programmed for another vehicle even if it has the same part number. You would need to have it reprogrammed if it could be. The ECM is programmed with a VIN number and cannot be programmed to another VIN. This is due to Theft deterrent built in. You will need to have a reprogrammed ECM put in with your VIN programmed into it.

hi, I need some help to decide weather to purchase a 2000 dodge ram 1500 magnum or a 2003 dodge ram 1500 small engine
ANSWER : On the 2000 magnum you can expect to pay $500 on tires. If the 2003 had an overheating issue, whether or not it get fixed is a concern. The 2003 is a newer vehicle even though it has 15k more miles. My best guess could possibly not be very accurate, since it comes down to the condition and how good they look to me.

I would recommend having a professional mechanic do a complete pre-purchase inspection on both trucks in order to give you an idea of the problems they may have. Afterwards you’ll have the information to make an informed decision.

Engine block rod came out. Now I need to change my engine.
ANSWER : The 3.7 liter V6 engine from the Liberty was also an option on the Wrangler. However, in order to replace the engine to a V6, replacement of the powertrain control module would be required to make this work. Different engine mounts, brackets, A/C and power steering lines, as well as electrical connectors may be required to make this work. Unless you are doing an engine swap for performance, I would recommend against doing this replacement considering all the work involved. If you can not find another four cylinder engine for your vehicle, unfortunately, it will likely cost much more to install the V6 and might be more beneficial to search for another vehicle

Engine swap details needed. I need to know if the swap will fit.
ANSWER : Hi there. When it comes to swapping engines for your vehicle, what you can do is check all of the engine mounts and transmission mounts and make sure that they will work. If the mounts are a little off but there is room, then you may have to retro fit a custom mount. Check the length of the engine and the transmission assembly together. Make sure that the assembly is the same length. It may be okay if it’s a few inches shorter or longer, however, it cannot exceed 3 inches or the assembly will not fit. There has to be room for the engine to move around. Also, keep in mind, the CV shafts may not match up to the transmission and wheel hubs, especially if the transmission is shorter or longer. If you need further assistance with swapping your engine with another engine, then seek out a professional, such as one from Your Mechanic, to help you.

Trying to change 2002 Dodge ram 1500 5.9 ltr engine with 2000 Dodge ram 1500 5.9 and motor mounts don’t line up
ANSWER : Hi there. Although the engines are the same size internally, it is very common for manufacturers to change the location of engine mounts both on the engine and the interior of the engine compartment. Unfortunately, this type of swap would require some fabrication of the motor mount location in order for it to fit correctly.

Check engine light refuses to go off after engine replaced
ANSWER : Hello there, you have a long series of issues going on with your 2013 Hyundai Sonata. If you keep getting a repeating oil light on than there is likely a fault in that system.

Since this fault has lasted after the engine was replaced it could be a oil pressure sensor, wiring harness fault, ECU fault, oil pump, oil strainer clogged, or low oil pressure.

To diagnose this issue properly you need a complete vehicle inspection to start from square one and identify the root cause of all this.

I have a 2004 Dodge Ram 1500 5.7 Hemi engine V8
ANSWER : Hi There,

It sounds like you may have a couple of separate issues going on here. The idling problem may suggest you have a dirty or faulty idle air control valve. The idle air control valve monitors the air intake as it is mixed with fuel prior to being injected into the engine at low speeds and at idle. This valve is controlled by the vehicle’s computer and will adjust idle speed based upon other measurements such as engine temperature, intake air temperature and electrical system load or voltage. This is also an important function when starting the motor as it allows the motor to run and idle on it’s own once the motor fires. When you accelerate, the engine RPM increases, and as you let off the gas, the RPM slowly returns to the normal idling speed with the help of the idle air control valve making the transition from a higher RPM back down to idle speed while adjusting the air/fuel ratio constantly to allow this to happen smoothly. When the engine RPM drops below the normal range of about ~800 RPM, this often times will cause the engine to stall indicating a dirty or faulty idle air control valve.

Blue smoke coming from your exhaust generally means that the motor is burning the engine oil. This can happen for a couple of different reasons such as worn piston rings or leaking valve guide seals. When this happens, the engine oil is burned in the combustion chamber along with the fuel which is what generates the blue smoke coming from the exhaust. I would recommend having an expert from YourMechanic come to your location to diagnose and inspect your vehicle.
